Abstract

The arrangement has driven control cams for the lifting motion of a lifting suction device and the drive motion of a trailing suction device. An additional pivotable control cam synchronizes the lifting and driving motions and sets the transition position of the sheet from lifting suction to trailing suction and the sheet transport height. The arrangement has a driven control cam for the lifting motion of a lifting suction device (19) and one for the drive motion of a trailing suction device (21) and an additional pivotable control cam that synchronizes the lifting motion and the driving motion. The pivotable control cam (44) sets the transition position of the sheet from lifting suction to trailing suction and the sheet transport height. The lifting and driving suction devices can be driven by separate cams.

Der Bogenstapel 8 liegt auf einer gesteuert anhebbaren Stapelplatte 10 auf. Die Entnahme der Bogen 7 erfolgt von der Oberseite des Bogenstapels 8 mittels eines sogenannten Saugkopfes 18, der unter anderem eine Anzahl von Hub- und Schleppsaugern 19, 21 für die Vereinzelung der Bogen 7 aufweist. Darüber hinaus sind Blaseinrichtungen 22 zur Auflockerung der oberen Bogenlagen und Tastelemente 23 zur Stapelnachführung vorgesehen. Zur Ausrichtung des Bogenstapels 8, insbesondere der oberen Bogen 7 des Bogenstapels 8 sind eine Anzahl von seitlichen und hinteren Anschlägen vorgesehen.The sheet stack 8 rests on a stack plate 10 which can be raised in a controlled manner. The withdrawal the sheet 7 takes place from the top of the sheet stack 8 by means of a so-called Suction head 18, which includes a number of lifting and dragging vacuum cleaners 19, 21 for the separation of the sheets 7. In addition, blowing devices 22 are Loosening of the upper sheet layers and sensing elements 23 for stack tracking intended. To align the sheet stack 8, in particular the upper sheet 7 of the Sheet stack 8, a number of side and rear stops are provided.

Der Saugkopf 18 weist eine Antriebswelle 25 auf, die in Gestellwänden 24, 26 des Saugkopfes 18 antreibbar gelagert ist. Der Antrieb kann entweder von der Maschine oder auch von einem separat gesteuerten Elektromotor aus erfolgen. The suction head 18 has a drive shaft 25 which in the frame walls 24, 26 of the Suction head 18 is drivably mounted.

Eine ebenfalls in den Gestellwänden 24, 26 des Saugkopfes 18 parallel zur Antriebswelle 25 gelagerte Drehachse 31 trägt nebeneinander angeordnet eine erste drehbar gelagerte Schwinge 32 für die Bewegung des Hubsaugers 19, eine zweite drehbar gelagerte Schwinge 33 für die Bewegung des Schleppsaugers 21 und eine dritte drehbar gelagerte Schwinge 34 für die Bewegung des Tastelementes 23.One also in the frame walls 24, 26 of the suction head 18 parallel to Drive shaft 25 mounted axis of rotation 31 arranged side by side supports a first rotatable mounted rocker 32 for the movement of the vacuum cleaner 19, a second rotatably mounted Swing arm 33 for the movement of the vacuum cleaner 21 and a third rotatably mounted Swing arm 34 for the movement of the feeler element 23.

Jede Schwinge 32, 33, 34 trägt an einem Arm eine drehbar gelagerte Steuerrolle 36; 37; 38, die mit der jeweiligen Steuerkurve 27; 28; 29 zusammenwirkt.Each rocker 32, 33, 34 carries on one arm a rotatably mounted control roller 36; 37; 38, with the respective control curve 27; 28; 29 cooperates.

Die Schwinge 32 ist am Ende ihres zweiten Armes gelenkig mit einem Hubsaugerträger 39 verbunden, der wiederum den Hubsauger 19 trägt. Die Schwinge 33 ist am Ende ihres zweiten Armes mit einem Schleppsaugerträger 41 verbunden, der wiederum gelenkig den Schleppsauger 21 trägt.The rocker 32 is articulated at the end of its second arm with a suction cup bracket 39 connected, which in turn carries the vacuum cleaner 19. The rocker 33 is at the end of its second arm connected to a vacuum cleaner carrier 41, which in turn the articulated Drag vacuum 21 carries.

Der Hubsaugerträger 39 weist eine drehbar gelagerte Steuerrolle 42 und der Schleppsaugerträger 41 eine drehbar gelagerte Steuerrolle 43 auf, die gemeinsam mit einer schwenkbar angeordneten Segmentkurve 44 in Abrollkontakt stehen.The suction cup carrier 39 has a rotatably mounted control roller 42 and the Drag cleaner carrier 41 on a rotatably mounted control roller 43, which together with a pivotally arranged segment curve 44 are in rolling contact.

Eine Druckfeder 46 zwischen dem Hubsaugerträger 39 und der Schwinge 32 stellt die Anlage der Steuerrolle 36 an der Steuerkurve 27 und der Steuerrolle 42 an der Segmentkurve 44 sicher.A compression spring 46 between the suction cup carrier 39 and the rocker 32 provides the System of the control roller 36 on the cam 27 and the control roller 42 on the Segment curve 44 sure.

Eine Druckfeder 47 zwischen dem Schleppsaugerträger 41 und der Schwinge 33 stellt die Anlage der Steuerrolle 37 an der Steuerkurve 28 und der Steuerrolle 43 an der Segmentkurve 44 sicher. A compression spring 47 between the vacuum cleaner carrier 41 and the rocker 33 provides the System of the control roller 37 on the control curve 28 and the control roller 43 on the Segment curve 44 sure.

Die Segmentkurve 44 ist um eine gestellfeste Achse 48 des Saugkopfes 18 mittels nicht dargestellter Stellmittel verschwenkbar gelagert.The segment curve 44 is not about a fixed axis 48 of the suction head 18 represented actuating means pivotally mounted.

Wie in Fig. 5 dargestellt, setzt der Hubsauger 19 zum Ansaugen und Aufnehmen des Bogens 7 auf dem Bogenstapel 8 auf. Der Schleppsauger 21 befindet sich zu diesem Zeitpunkt an seinem Wendepunkt am Ende der Schleppbewegung. Nach erfolgtem Ansaugen des Bogens 7 wird dieser vom Bogenstapel 8 abgehoben und, wie in Fig. 6 dargestellt, in eine Übergabeposition gebracht. Diese Übergabeposition weist eine einstellbare Höhe gegenüber dem Bogenstapel 8 auf. Hierbei wird der Hubsauger 19, der während der Ansaugphase parallel zur oberen Lage des Bogenstapels 8 ausgerichtet war, um einen kleinen Winkel α (α = ca. 10° bis 35°) gegenüber der oberen Lage des Bogenstapels 8 geschwenkt. Durch diese Maßnahme wird die Hinterkante des zu transportierenden Bogens 7 etwas angehoben, so daß ein Tragluftstrom von den vorgesehenen Blaseinrichtungen 22 unter dem Bogen 7 aufgebaut werden kann.As shown in Fig. 5, the vacuum cleaner 19 sets for sucking and picking up the Sheet 7 on the sheet stack 8. The vacuum cleaner 21 is to this Time at its turning point at the end of the towing movement. After that Sucking the sheet 7 is lifted off the sheet stack 8 and, as in FIG. 6 shown, brought into a transfer position. This transfer position has a adjustable height compared to the sheet stack 8. Here, the suction cup 19, the was aligned parallel to the upper layer of the sheet stack 8 during the suction phase, by a small angle α (α = approx. 10 ° to 35 °) with respect to the upper layer of the Sheet stack 8 pivoted. By this measure, the rear edge of the transporting sheet 7 slightly raised so that a stream of air from the provided blowing devices 22 can be built under the arch 7.

In Fig. 2 ist die Übergabeposition, in welcher der Schleppsauger 21 auf den Bogen 7 aufsetzt, dargestellt. Der Schleppsauger 21 ist hierbei ebenfalls um den Winkel α gegenüber der oberen Lage des Bogenstapels 8 geneigt.2 is the transfer position in which the drag vacuum cleaner 21 is on the sheet 7 touches down, shown. The drag cleaner 21 is also at the angle α inclined relative to the upper layer of the sheet stack 8.

Von der Übergabeposition aus führen nunmehr Hubsauger 19 und Schleppsauger 21 eine gemeinsame Transportbewegung aus. Hierbei rollen die Steuerrolle 42 des Hubsaugerträgers 39 und die Steuerrolle 43 des Schleppsaugerträgers 41 auf der gemeinsamen Segmentkurve 44 ab.From the transfer position, now suction lifters 19 and drag vacuums 21 lead one common transport movement. Here, the control roller 42 of the Hubsaugerträger 39 and the control roller 43 of the Schleppsaugerträger 41 on the common segment curve 44.

Das hierbei entstehende relativ große Zeitfenster wird für die korrekte Bogenübergabe genutzt. Nach diesem gemeinsamen Transportweg beginnt der Schleppsauger 21, wie in Fig. 3 dargestellt, seine Vorwärtsbewegung. Nachdem die Hinterkante des Bogens 7 den Hubsauger 19 vollständig passiert hat, setzt dieser auf dem Bogenstapel 8 auf, um den nächsten Bogen 7a anzusaugen. The resulting relatively large time window is used for the correct sheet transfer used. After this common transport route, the vacuum cleaner 21 begins, as in FIG Fig. 3, its forward movement. After the trailing edge of the sheet 7 den Vacuum cleaner 19 has completely passed, this is on the sheet stack 8 to the to suck in the next sheet 7a.
